Application filed March 25, 1824. Serial No. 701,652.

This invention relates to pressing and ironing machines and particularly to improvements in power operated pressing machines.

An object of the invention is to produce a pressing machine having a high compression factor and capable of subjecting work to heavy pressure; and likewise it is an object to produce a machine safe to operate and which is under the control of the operator at all times.

The pressing machine embodies a new and improved combination and preferably employs a prime mover or power means located in the upper portion of the pressing machine which delivers its pressing stroke downwardly upon a power thru t toggle which operates a lever to impose pressure between the contacting pressing members or jaws which are first closed manually by the operator. My improvements in pressing machines embody the additional feature of having wide opening pressing jaws, and, to this end, the press head is caused to move upwardly a long distance thereby alfording a wide open clear space which permits the operator to conveniently work while spreading the garment or other work on the buck to be pressed.

The accompanying drawings show a preferred form of the invention illustrating the new combination and arrangement of parts making up my invention, and it is understood that certain changes in arrangement and mode of operation may be carried out without departing from the scope of the invention. Y

Figure 1 shows a front elevation of the machine in closed position.

Figure 2' illustrates a side view of the pressing machine shown in closed position under final high pressure, and the press is shown in open position by dot and dash lines.

Figure 3 shows a detailed fragmentary View of the motor means and cooperating thrust or power toggle shown in position ready to produce final pressure.

Referring further to the drawings for a detailed" description of the invention, there is shown a pressing machine frame 10 supporting a lower pressing buck 11. A press lever 12 is pivoted at 13 on the frame and the forward end thereof is attached to a press head 14 which rises and falls in relation to the back. The rear end of the press lever 12 is provided with a counter-balancing weight 15 which may be just a little heavier in some instances than the head 14 thereby causing the machine to stand normally open. Furthermore the weight 15, or a tensionspring or other appropriate means, causes the head 14: to lift off the work when the operator manually kicks down on a kick-- off pedal means to be described.

A lever 1718 is pivoted at 19 in the frame with the upper part 17 extending upwardly to connect with a toggle link 20. This lever is preferably L-shaped to simplify the construction, and the link 20 is pivotally suspended from the rear end of the press lever 12 while its lower end is. pivotally connected to the upper end of the lever link 17 and thus it is observed how the 1 parts 17 and 20 constitute a toggle which breaks rearwardly from the frame to lift the head 14 high from the buck and which moves forwardly toward straight position closing the head down upon the back. The lower part 18 of the lever extends forwardly and substantially horizontally towards the front of the pressing machine and connects with the power means employed to impose highcompression between the pressing jaw surfaces.

A handle bar 21 is carried by the pressing head or lever and overhangs the front margin of the head and is thus convenientlylocated to the operator who grasps with one. hand the handle and draws down the head to bring the pressin members 14 and 11 into light contact, an the other hand of the operator is simultaneously employed, to operate the motor means as will be explained, so that both hands are engaged away from the press jaws. It is to be appreciated that the operator necessarily must employ his hands to close the hea upon the work and a ply heavy pressure to the head and there ore this construction compels the operator to remove his hands-from the region of the pressing jaws for the purpose of closing the press and thus the factor of safety is increasedto the int where it is practically impossible for t e operator to accidently injure his hands by leaving them in, the press too long when the machine is placed 1n operation. 7

Any suitable motor means inthe form. of

an electric motor 25 is installed in the upper portion of the pressing machine and drives a shaft 27 provided with a fly-wheel 26 and said drive shaft rotates a worm pinion 28 engaging with a worm wheel 29 driving a power shaft 30 at reduced speed with increased power output. I

A control handle 31 oscillates a shaft 32 which swings a weighted trip 33 in and out to engage a clutch lever 34. I The clutch lever has connection with a clutching mechanism contained within the gear housing 35 whereby the operation of the power shaft 30 is placed-under the control of the operator.

The operator depresses the handle 31 which swings the weighted trip 33 outwardly thus engaging the clutch lever 34 through the agency of a trip 24 pivoted on the weighted member 33 which acts to move the clutch lever 34 and throw the shaft 30 into driving connection with the worm wheel 29 to cause the said power shaft, together with a cam or eccentric 36 fixed thereon, to be picked up by the motor shaft 27 and rotated through amovement of 180 degrees. Thus the cam 36 is driven to its lowermost position by actuating the control handle 31 and remains there until the operator again depresses the handle whereupon the cam 36' is driven upwardly 180 d agrees to its original position. The handle 31 returns to a normally upward position each time it is depressed and released by the operators hand because the weighted endulum member 33 and its trip 24 moves llack past the top end of the clutch lever 34. The motor 25 with the fly wheel 26 run continuously and the fly wheel possesses sufficient momentum to assist the power member or cam 36 to drive downwardly with a powerful revolving stroke under the most trying conditions of heavy pressing.

A power thrust toggle consists of links 40 and 41 having their adjacent ends connected by a pin 42. In the present design, the pin 42 is anchored in the upper end of the link 41 and moves freely in a short slot 43 made in the lower end of the link 40. Thus 1 provide a freely floating lost motion connection 42-43 between the links constituting the toggle 40-41 The upper end of this toggle is pivotally swung'or suspended on the cam 36 while the lower end of the toggle is pivoted at 44 to the lever 18. Some suitable .form of manually operated kick-off means is employed for breaking the toggle 4041 forwardly to cause the press to open, and in this instance I show a pedal 45 integrally made with the link 41. This kick-oil pedal extends forwardly to a position convenient to the operator and by thrusting downwardly on the pedal the operator causes the press to quickly open.

Automatic means are employed to straighten the power thrust toggle 40-41 and in the present machine this device takes the form of a weighted arm 47 extending outwardly from the upper end of the link 40. It is to be understood that the upper end of the link 40 is constructed in the form of an eccentric strap to encompass the eccentric driver 36 and I preferably construct the arm 47 integrally with this eccentric strap. The function of the arm and weight 48 is to urge the links 40 and 41 rearwardly and thus the action of the weight pressing downwardly to swing the toggle link 40 clock-wise very readily accomplishes this purpose because the lost motion connection 42-43 permits a slight freedom of motion in the linkage thereof suificiently to cause the thrust toggle center pin 42 to move clock-wise until the center line position thereof is passed. At one stage of the straightening movement of this thrust toggle, the center pin 42 moves into exact alignment with the plane of the power shaft 30 and pivot pin 44, and it is desirable that this centcr line position be slightly passed in order that the toggle reach an over-straightened position to set the parts in locked relation. A reach lug 50 is made-integrally with one of the toggle links, as for example, the link 40. This lug reaches past the center pin 42 and engages the face of the lower link 41. A screw 51 carried by the reach lug 50 is adjusted so that the center pin 42 stops at a fixed point on an overstraightened position and thus the thrust toggle 40 and 41 is so set up and constituted that a heavy thrust may be transn'iitted therethrough withoutdanger of the toggle breaking open during the high pressure thrust exerted by the cam and motor.

In the operation of the machine, assuming that the head is up the operator draws the head down manually to contacting position under light pressure which causes the toggle 2017 to approach straight position but this toggle is usually adjusted so that it does not quite reach a straight line position. for, by causing the links 20 and 17 to remain normally in angular relation to each other. it follows that this toggle collapses rearwardly more quickly by the. downward pull of the weight 15 when the press begins to open. The jaw or head closing action causes the toggle 40-41 to move into a straight line position, and the weight 48 places this toggle in an over-straightened locked position whereupon the operator presses downwardly on the handle 31 causing the crm 36 to drive downwardly on the thrust toggle to produce high compression between the head and buck. The machine is now opened by again operating the clutching mechanism by pressing down on the handle 31 which causes the cam 36 to rotate to its uppermost position as shown in Figure 3 whereupon the operator depresses the pedal 45 which breaks or collapses the toggle '4041 forwardly thus causing the weight 15 to quickly open the machine. A

safe to operate because the operator must. "close the press with one hand and throw in the clutching mechanism with the other. The

power parts are all installed in the up er, p part of the press which is an advantage e-- cause the lower framework does not have to be so heavily constructed and the motor parts are lesslikely to pick up dirt from I the floor on which the press rests.
